What replay_stop does on TradingView MCP Bridge
AI agents invoke replay_stop to trigger actions in TradingView MCP Bridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why replay_stop is rated High
This tool executes a command that changes application state rather than simply reading data. While the action is reversible and has minimal blast radius (stopping a replay is a benign operation with no destructive or financial consequences), it meets the definition of Execute because it triggers an external operation whose effects depend on when it is invoked.
From the tool's definition Tool name: 'replay_stop'. Description: 'Stop replay and return to realtime'. This triggers an action that changes the state of the TradingView application—halting a replay operation and switching the chart to realtime mode.
